So I found my shiny seed, calibrated the starting PID frame, and was all set to RNG this. I attempted it about four times, and didn't get it once.. so I called it a night and went out and had a couple of drinks :D. I then get home in a slightly drunken state, and decide to try one more time.. and got it! Being drunk = easy RNG abuse with this Pokémon, and that's why it's in my trophy case :).
